Quantum physics work function
WebConsider the electrons in a metal as trapped inside an ‘energy well’ where the energy between the surface and the top of the well is equal to the work function Φ. A single electron absorbs one photon. Therefore, an electron can only escape the surface of the metal if it absorbs a photon which has an energy equal to Φ or higher.
